Fixes #2267.

This PR doesn't decrease the coverage, because every job is tested either per PR or
nightly run (instead of 2 times as it was before). Actually, it even increases it because
Android is tested with Ubuntu 20 now which was disabled before.
This PR adds tests for #2219 by changing the `compilation_on_android_ubuntu.yml` workflow.
The first run will take about two hours, since LLDB is built from scratch. Later, the build is
cached and the whole job should not take more than three minutes.

Core of the PR is an integration test that boots up vscode and lets it debug a test WASM file.
Since building the extension now depends on node >=16 (see #2292),
build_wamr_vscode_ext.yml will fail on the next release without this change.
Move the native stack overflow check from the caller to the callee because the
former doesn't work for call_indirect and imported functions.

Make the stack usage estimation more accurate. Instead of making a guess from
the number of wasm locals in the function, use the LLVM's idea of the stack size
of each MachineFunction. The former is inaccurate because a) it doesn't reflect
optimization passes, and b) wasm locals are not the only reason to use stack.

To use the post-compilation stack usage information without requiring 2-pass
compilation or machine-code imm rewriting, introduce a global array to store
stack consumption of each functions:
For JIT, use a custom IRCompiler with an extra pass to fill the array.
For AOT, use `clang -fstack-usage` equivalent because we support external llc.

Re-implement function call stack usage estimation to reflect the real calling
conventions better. (aot_estimate_stack_usage_for_function_call)

Re-implement stack estimation logic (--enable-memory-profiling) based on the new
machinery.

Discussions: #2105.
